This invention relates to anti skid tire chain fasteners and has for its objects to provide an improved and simplified means whereby such a fastener can be produced at low cost, and be easily manipulated for application and removal by the user. Other According to the invention an end link of a rim or side chain has pivoted to ita cam lever provided with a projection at its free end said cam lever being firsthooked into the linkof the other end of the side or rim chain and then engaged with a sliding keeperlink transversely embracing the link next adjacent that carrying the cam lever.

The invention is embodied in the example herein shown and described the features of novelty being finally claimed.

In the accompanying drawings:

Fig. 1 illustrates in side view the two ends I of a side chain one of which is equipped with the fastener lever placed in the end link of the other end according to the invention.

Fig. 2 shows the fastener leverdrawn down into position preparatory to having the keeper app-lied.

Fig. 3 shows the keeper applied. a

Fig. 4 is a top plan view of Fig. 3 showing the keeper applied. I

Fig. 5 is a cross section ofthe link of the chain carrying the keeper with the keeper in full lines.

Fig. 6 illustrates how the chain is flexed and the keeper twisted to efiect the connection or disconnection of the ends of the side chain.

is straightened, as in use, the lever is retained 1n the fastening position. i

In practice the keeper link 12 is first passed over the lever onto its link of the chain and insertion in the end link of the other end of the side chain is" drawn toward the end containing the keeper thereby applying cam action a up slackin the chain.
